Doctrine supports enumType on array values, while the current implementation always assumes the value to be an enum object, if enumType is set.

If $typeOfField is `json_array` the collectionKeyType will still be null, while collectionValueType will be filled. That's because we have no way to determine from doctrine metadata, if the key is string or int. Yet I don't know if that's a valid thing to do, otherwise we should return null in that case.
